Alright all you smart people:

Regarding related rates,

Assume x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt .

Equation: xy = 4

Find: dy/dt when x = 8

Given: dx/dt = 10

and

Find: dx/dt when x = 1

Given: dy/dt = -6

Please someone shed some light!
